Browser Extensions

or, superpowers for your browser

This means that you can customize your browser with the features that
are most important to you. Think of extensions as ways of adding new
superpowers to what the browser can already do.

These superpowers can be mighty or modest, depending on your needs. For
example, you might install a currency converter extension that shows up as
a new

button next to your browser’s address bar. Click
the button and it converts all the prices on your current web page into
any currency you specify. That’s helpful if you’re an avid backpacker who
does most of your travel planning and booking online. Extensions like these
let you apply the same kind of functionality to every web page you visit.
